SUMMARY:GRACE Hackweek 5
DESCRIPTION:An online school on time-variable gravity from GRACE and GRACE-FO satellite missions\nSatellite gravimetry has become an indispensible tool for studying the earth system. The satellite missions CHAMP\, GRACE/GRACE-FO and GOCE along with Satellite Laser Ranging have demonstrated the utility of time-variable gravity data in understanding the mass changes and their transport within and between the hydropshere\, cryosphere\, atmosphere\, oceans and the solid earth. \nThe challenging aspects of satellite gravimetry are the recovery of time-variable gravity from observations due to the low signal- to-noise ratio\, and the use of time-variable gravity data by non- geodesists. It is our aim in this online school to give an idea of the time variable gravity field recovery process from satellite gravimetry missions\, and also to help non-geodesists to get to grips with handling time-variable gravity data from GRACE/GRACE-FO. \nThe online school is open to everyone interested in using time- variable gravity for their research. Certificates will be issued to participants who complete all the labs. We look forward to your participation and a fruitful online school. The last date of application is September 19\, 2025 (UTC). \nRegistration: https://forms.office.com/r/WzP7GdBbwk \nMore Info: GRACE Hackweek 5 – Program \n  \nOrganizing Committee: \nProf. Balaji Devaraju (IIT Kanpur\, India); Prof. Nico Sneeuw (Uni. Stuttgart\, Germany); Prof. Matthias Weigelt (Leibniz Uni. Hannover\, Germany)

SUMMARY:South African National Geodesy Workshop
DESCRIPTION:Towards a National Geodesy Working Group for South Africa  \nGeodesy — the science of measuring the Earth’s shape\, orientation\, gravity field\, and changes over time — is the foundation of modern mapping\, positioning\, land administration\, infrastructure\, and climate monitoring. \nSouth Africa has a proud history in terrestrial and space geodesy\, from early triangulation networks to today’s NRF Space Geodesy facilities\, TrigNet GNSS stations\, tide gauges\, and participation in global collaborations. Yet\, our efforts remain fragmented across institutions\, with limited coordination. \nIn 2015\, the United Nations adopted Resolution A/RES/69/266 on the Global Geodetic Reference Frame for Sustainable Development (GGRF)\, calling on all countries to strengthen geodetic infrastructure\, skills\, and governance. South Africa must respond by aligning nationally and globally. \nTo this end\, a National Geodesy Workshop will be convened to: \n\nBring together key stakeholders in geodesy.\nStrengthen coordination of infrastructure\, data\, services\, and skills.\nAlign with the UN-GGRF agenda.\nEstablish a National Geodesy Working Group as a formal coordination mechanism.\n\nThis is an exciting step towards ensuring that South Africa continues to play a leading role in geodesy\, contributing both to national development and the global community.

SUMMARY:5th IVS Training School on VLBI for Geodesy and Astrometry
DESCRIPTION:The aim of this training school is to prepare for the next generation of VLBI\, both in terms of technical development and knowledge transfer between generations of researchers. The new VLBI Global Observing System (VGOS) is being installed worldwide and continues to develop.  VGOS promises significant improvement in the accuracy of VLBI results.  Thus\, VGOS will be of great importance for geosciences and global change research as part of the Global Geodetic Observing System (GGOS). \nThe successful development of VLBI technology in the future requires training and educating the young generation of scientists and their familiarization with all aspects of VLBI technology\, starting with VLBI station instrumentation receiving and converting the radio signal\, data processing and analysis and obtaining the final results\, such as Terrestrial and Celestial Reference Frames and Earth Orientation Parameters. \nThe IVS Training School is organized by the IVS Committee on Education and Training (IVS CTE)\nDetails about the school will be made available in due time on the website:\nhttps://www.maanmittauslaitos.fi/en/about-nls/organisation/cooperation-groups/ivs-committee-education-and-training/5th-ivs-training\nFor further information contact Nataliya Zubko (firstname.lastname@nls.fi) \nEvent Category: ivs
